To all whom t may conce/m:

Be it known that I, ELI A. GUTHMAN, a citizen of the United States, and a resident of the city of New York, Bensonhurst, borough of Brooklyn, in the county ofKings and State of New York, have invented anew and Improved Safety-Razor, of which the following is a full, clear, and exact description. 1

Among the principal objects which the present invention has in view are to amplify A the available' cutting edges of a razor of g been removed and the handle relaxed to y the character specified; to provide a holder adapted for ra id and ready adjustment of the blades to p ace the various cutting edges in service position; to simplify the construction and arrangement of the 'holder and parts constituting the same; to simplify the individual blade-holders; and to provide a construction the parts whereof are readily accessible for clea purposes.

ln. the drawings, igure 1 is a section taken as on the l 1-1 in Fig. 7; Fig. -2 is a section taken as on the line 2-2 in Fig. 1; Fig. 3 isa view similar to Fig. 1, except that the blades and clamps therefor have spread the sides of the frame; Fig. l is a side view of the y,blade-holder and blade shown as being revolved on the pivots of the holder, lthe frame being relaxed to permit the same; Fig. 5 is a'detail view on an enlarged scale, in section, taken as on the line 5--5 in Fig. 4; Fig. 6 is a detail view on an enlarged scale, in section, taken as on the line 6-6 in Fig. 1; Fig. 7 is an end view of a razor constructed and arranged inaccordance with the present invention, the parts being shown in service relation; Fig. 8 is a longitudinal section taken as on the line 8-8 in Fig. 9, showing a modified forml of the blade-holder and frame therefor; Fig. 9 is a flat side view of the same; Figs. 10 and 11 are detail views showing the separable coperating plates forming the bladeholder shown in Figs. 8 and 9; Fig. 12 is a fiat face view, showing a modified form of the blade-holder and the blade disposed thereon.

As seen in the drawings, the blades 17 in the present invention are what are known as the Wafer type, and are provided with two oppositely-disposed cutting edges. ln the present invention, two such blades are employed. Each of the blades is vindependently and primarily held in a separate holder. Each of the holders consists primarily of a cover plate 18 and a bed plate 19. The plates 18 and 19 are each provided with half-section pivot `pintles 20, upon which the holders revolve when locked up and when suitably mounted. Each'bed plate 19 is provided with elongated. alined bosses 21, and at one end of said plate are overhanging clips 22. Each cover plate 18 is provided with slots 23, placed and formed to receive in coperative relation said bosses 2 1, to therewith form guides Jfor the sliding of. the cover-plateover the blade 17 when held on the plate 19. The cover plate 18 is similarly provided with clips 24:, as best shown by the dotted lines in Fig. 4: of the v 19, erforations being provided in the blades t over the bosses 21, to therewith hold to the blades against displacement. The cover plate 18 is then placed over the blade, the slots 23 of said plate being iitted over the bosses 21. When the plate 18 is thenmoved so as to extend its Afree end under the clips 22, the clips 24: of said cover plate extend under, to hold the bed plate 19.v In this position, the two half sections provided on each of the plates coincide to ormthe pivot pintles 20. The blades are disposed in the holders, and said holders are handled independently, for adjustment in the holding frames.

cross piece 26. The cheek pieces 25 are each provided adjacent the upper edge thereof with inwardly-opening grooves 27. The grooves 27 in each cheek piece are disposed in angular relation, the angle being such as the needs of the construction, or the fancy of the designer dictates. rlhe grooves 27 in `the opposite cheek pieces coincide, said grooves being provided to receive and hold the end lugs 28 with which the plates 18 and 19 are both provided. Centrally disposed in the grooves 27 are circular perforations 29, as best seen in Fig. 3 of the drawings, through which the pintles 20 extend, said perforations forming bearings for said pintles.

-The cheek pieces 25, as shown best in Fig. 4 of the drawings, are extended from the j crossA piece 26 at an angle of less than 90.

The cross piece 26,- as `illustrated in said l igureof the drawings, is normally bowed .end of a handle 31. As seen in Fig. 4 of the drawings, 'itis preferred that when A'the handle 31 is manipulated to vrelax the cross piece 26, the cheek pieces 25 are in osition to receive and hold the pintles 20.

l practice, it is required that the cheek pieces 25 -be slightly spread to; permitthe introduction of the pintles into the perforations 29. When'the holders formed bythe .plates 18 and 19 are then swung on the pintles 2 0 t0 coincide the lugs 28 with the grooves 27,

'thenatural spring of the cheek pieces? 25 movesthe groove-provided ends thereof to infold said lugs, to thereafter lightly maintain the` holders and plates contained therein in service, position.

The handle 31 is provided with a collar 32 to normally bear against the back of a rigid brace-plate .33. The plate 33 being rigid, when the handle 31 is manipulated, the boss and'center of the cross piece 26 are drawn toward the plate 33. This arrangement of the cross piece 26 increases the pressure of thecheek pieces 25 on the lugs 28 of the blade-holders, and serves to' more `rigid1y maintain said holders in their relation.

' With a razor thus c0nstructed,the operation is as follows: The blade-holders, if held between the cheel pieces 25, are removed therefromv lby spreadingthe ends vof said cheek pieces. The plates aremoved relative to each other until the clips 22 and 24 become disengaged lfrom` the adjacent plates. The

'cover plates 18 are removed from the. bed

plates 19, and blades 17 .are adjusted on the bed plates with reference to the bosses 21 thereon. The cover plates arethen disposed over said blades in register with the bosses 21, and the two plates are then moveduntil theA clips 22 and 24 engage the adjacent plates. Thehandle 31and the cross piece 26 connected therewith being relaxed, the cheek pieces 25 are spread, to admit the pintles 20 to the perforations 29. The blade-holders are rotated until the lugs 28 register and pass .within the gi'ooves'27. The handle 31 is then'manipulated to straighten the cross piece 26, and'increase the tension ,ofA the cheek pieces 25 on the blade-holders. The razor is now vin condition for use. If, dura ing the employment of the razor, it be desired to present the edges of the blades 17 opposite to those which have been used, the handle 31 is manipulated to relax the tension of the cross piece.26 and the cheek pieces 25 lsuiiciently to permit the blade-holders to be rotated.` The holders are then rotated to present the hitherto unused edgesv of the blades 17, when the holders are locked in .operative position by manipulating the handle 31.

` In Figs. 8 to 11 of the drawings, a modilied form of the holder is shown. The modilication consists in providing a cover plate 34, whichV is furnished with hook-like knuckle members 35 arranged to enfold and swing underand around the inset edges 36 of a bed plate 37, as shown best in Figs. 10 and 11 of the drawings. 'Ifhe cheek pieces 25, when used in conjunction with this m0di' ed form of the blade-holder, are provided with enlarged grooves to replace the grooves 27, said grooves being formed by hook-shaped edges 38 on said cheek pieces. In the modified form, the cover platet34 swings lengthwise above `the bed plate'37,

and is ,provided with circular perforations .39, which register with the bosses 21, and do not slide relative thereto asin the preferred form ofthe invention. To hold-the plate 34 in service relation to the bed'plate 37 -and blade when held therebetween', the bedfplate 37 is provided with hook-shaped latches 40,

under whichthe free. end of the' plate 34 snaps, when closed in service position, as

shown bestl in Figs. 8 and 9'. To lift the plate 34 from the service position, it is provided with a fingerclip 41, suiiiciently raised from the exposed surface of the' plate34to be engaged by the fingers of the operator, to draw'the plate out of engagement with the latches 40. In operation, the modified form' of the invention rotates about the pintles 42 with which the bed plate 37 only is provided. The operation of the apparatus, when constructedv in accordance with the modified form above described differs from the operation of the preferred form -only'in that the cover plate maybe lifted to expose the cutting blade to permit its removal without disengaging the bed plate 37 from the cheek plates 25.

In Fig. 12' of the drawing a further modification of the invention is shown.

.which consists in providing a base plate 43 with elongated plates 44 and` a cross guard piece 45. The bed plate thus provided, as will be seen, permits the intr duction of the blades 17 to serviceposition, o thereafter held by the spring tension of the clips 44. In this form of the invention, it will be noted that the cover plate asa separate element vfrom the .bed plate, is omitted.
